IOW heavier objects are harder to start and stop turning than lighter ones.

Then there is what is called polar moment of inertia, which is where the weight is located. Using a barbell as an example, it is easier to turn a 100lb barbell when the weight is in the center of the bar than with the weight at the ends. Which is why a midengined car turns easier than a similar over all weight front engined car. the closer you can concentrate your weight at the CG the easier it is to turn.
